What is this tool?

Cron expressions schedule recurring jobs in Unix-like systems and many orchestration tools. This builder edits the classic 5 fields (minute, hour, day of month, month, day of week), explains them in plain English, and estimates the next run times in your local timezone. It supports *, lists, ranges, and steps.

How to use it

  1. Use Visual builder to edit each field, or Explain expression to paste an existing cron string.
  2. Copy the generated 5-field expression into your scheduler.
  3. Check the next 5 local run times to confirm the schedule.
